Firearm suppressor with wave-splitting lattice

ABSTRACT

A firearm suppressor is described herein. The firearm suppressor can include a proximal end, a distal end, and a cylindrical body positioned between the proximal end and the distal end. The cylindrical body of the firearm suppressor can include one or more chambers and one or more chamber separators. The distal end can include spiral vanes and exhaust openings that can generate rotational force on the firearm suppressor by redirecting flow of gases exiting the firearm suppressor. The chambers can house a lattice structure in a form of lattice that can split sound waves, pressure waves, and quickly dissipate heat generated within the firearm suppressor.

INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS

Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference under 37 CFR 1.57 and should be considered a part of this specification.

FIELD

This invention relates broadly to firearm suppressors (e.g., silencers), and more particularly to a firearm suppressor with improved heat, sound and spark dissipation and lattice structure that provides improved dissipation of heat, pressure and sound.

DESCRIPTION OF THE RELATED ART

There are a number of gun suppressors on the market having various baffles and intermediate spacers mounted in outer tubes thereof. However, existing suppressors have a variety of drawbacks. For example, many of these gun suppressors do not provide sufficient heat dissipation, causing the suppressors to overheat. The heat generated from firing ammunition can accumulate and often cause heat related distortions and baffle strikes during use, which can degrade performance of the suppressor and negatively affect the trajectory of the projectile. This is especially true for firearms capable of rapid fire, such as automatic and semiautomatic firearms (e.g., high caliber machine guns). Further, some suppressors are heavy, thereby disturbing gun balance and preventing automatic and semiautomatic weapons from properly cycling. In addition, many prior art gun suppressors do not significantly reduce muzzle flash.

Another drawback of existing firearm suppressors is that they do not achieve adequate noise attenuation. Members of the armed services often suffer from some degree of hearing loss during tours of duty due to the noise generated by firearms during battles.

SUMMARY

It is, therefore, an object of this invention to prove a firearm suppressor with improved heat dissipation (e.g., heat generated while simultaneously cycling automatic and semiautomatic weapons), is not unduly heavy, and provides improved pressure/sound wave-splitting. Such improvements can prevent heat related distortions during use and noise related injuries.

DETAILED DESCRIPTION

Although certain embodiments and examples are described herein, this disclosure extends beyond the specifically disclosed embodiments and/or uses and obvious modifications and equivalents thereof. Thus, it is intended that the scope of this disclosure should not be limited by any particular embodiments described below.

The various examples of firearm suppressors described herein may optionally be printed (e.g., using an additive manufacturing process), single piece suppressors. In some examples, the example suppressors may be single, unitary piece or device. The various components, parts, and features of example firearm suppressors described herein may be printed together with the suppressor. In some implementations, examples of firearm suppressors described herein may not include modular components, parts, features, or the like.

FIGS. 1A-1L show a firearm suppressor (or suppressor) 100. The firearm suppressor 100 may include a proximal end 102, a distal end 104, and a body 106 positioned between the proximal end 102 and the distal end 104. The proximal end 102 may include a mating portion 108 that can define a proximal cavity 110. The distal end 104 may include one or more exhaust openings 112, a distal opening 122, one or more vanes 124, and a distal cavity 126.

The mating portion 108 can couple to a distal end of a firearm. When the mating portion 108 is coupled to the distal end of a firearm, the proximal cavity 110 may be in fluid communication with a cavity of the firearm such that a projectile (for example, a bullet) may travel from the firearm and pass through the firearm suppressor 100. In some implementations, the mating portion 108 may include threads formed on its inner or outer surface such that the mating portion 108 may be rotatably coupled to a firearm. In some implementations, the mating portion 108 is coupled to a firearm using suitable pressure coupling mechanisms. Other suitable couple methods or mechanism may be used to couple the mating portion 108 with a firearm (e.g., a key-slot mechanism).

In some implementations, the mating portion 108 may be circular in shape as shown in FIG. 1A. In some implementations, the mating portion 108 may have a suitable shape to be coupled to a distal end of a firearm.

In some implementations, the mating portion 108 may include a groove 114 formed on its inner surface, as shown in FIG. 1D. The groove 114 may be formed and extend around the entire inner circumference of the mating portion 108. In other implementations, the groove 114 may be formed around a portion of the inner circumference of the mating portion 108. In operation, the groove 114 may mate with a corresponding ridge of a firearm to further strengthen the mechanical coupling between the firearm suppressor 100 and the firearm.

Exhaust Openings and Vanes

The exhaust openings 112 may be formed on an outer circumferential edge of the distal end 104 of the firearm suppressor 100. The exhaust openings 112 may be positioned such that each of the exhaust openings 112 may be regularly or not regularly spaced from adjacent exhaust openings 112. In the example illustrated in FIG. 1A, a single row of the exhaust openings 112 may be formed on the outer circumferential edge of the distal end 104. In other implementations, the firearm suppressor 100 may include one or more rows of the exhaust openings 112.

In some implementations, the exhaust openings 112 may be in fluid communication with exhaust cavities 112A (see FIG. 1I), which may allow gas to escape from the inside of the firearm suppressor 100. As described herein, when a projectile (for example, a bullet) travels through the firearm suppressor 100, it may generate positive pressure within the firearm suppressor 100. Such positive pressure may push gases out from the inside of the firearm suppressor 100, for example, via the exhaust openings 112. Advantageously, the exhaust openings 112 may be angled or sloped towards the distal end of the suppressor 100 and/or in a counter-clockwise direction (when viewed from the proximal end 102 of the firearm suppressor 100) such that gases exiting the exhaust cavities 112A via the exhaust openings 112 may generate or exert a rotational force on the firearm suppressor 100. Such rotational force may bolster the connection between the firearm suppressor 100 and a firearm to which the firearm suppressor 100 is coupled (e.g., by exerting a rotational force on the body 106 in a direction that maintains and/or increases a coupling force of the suppressor 100 on the firearm).

In some implementations, the exhaust openings 112 and the exhaust cavities 112A allow improved pressure control within the distal chamber 142 and the rest of the firearm suppressor 100. By allowing air to exit the distal chamber 142 and the firearm suppressor 100 other than through the distal opening 122, the exhaust openings 112 and the exhaust cavities 112A can provide improved air flow profile within the firearm suppressor 100.

In some implementations, the exhaust cavities 112A and the exhaust openings 112 may have circular cross-sections. The diameter of the circular cross-sections may be between about 0.01 inches and about 0.1 inches, between about 0.02 inches and about 0.09 inches, between about 0.03 inches and about 0.08 inches, between about 0.04 inches and about 0.07 inches, between about 0.05 inches and about 0.06 inches, or about 0.01 inches, about 0.02 inches, about 0.03 inches, about 0.04 inches, about 0.05 inches, about 0.06 inches, about 0.07 inches, about 0.08 inches, about 0.09 inches, about 0.1 inches, or a range between any two of aforementioned values. In other implementations, the exhaust openings 112 and cavities 112A can have other suitable shapes (e.g., oval).

In some implementations, the exhaust cavities 112A may angularly be spaced apart from each other. As shown in FIG. 1H, the exhaust cavities 112A may be spaced apart from adjacent cavities at an angle, for example angle (3. The angle between each exhaust cavities 112A may vary based at least in part on the number of exhaust openings 112 and the exhaust cavities 112A. In some implementations, the angle between each exhaust cavities 112A (or the exhaust openings 112) may be between about 4 degrees and about 15 degrees, between about 5 degrees and about 14 degrees, between about 6 degrees and about 13 degrees, between about 7 degrees and about 12 degrees, between about 8 degrees and about 11 degrees, between about 9 degrees and about 10 degrees, or about 4 degrees, about 5 degrees, about 6 degrees, about 7 degrees, about 8 degrees, about 9 degrees, about 10 degrees, about 11 degrees, about 12 degrees, about 13 degrees, about 14 degrees, about 15 degrees, or a range between any two of aforementioned values.+

In some implementations, the exhaust cavities 112A, for example, as shown in FIG. 1I, may be angled with respect to the outer edge of the body 106. In some implementations, the angle (for example, denoted as a in FIG. 1I) between the exhaust cavities 112A and the outer edge of the body 106 may be between about 10 degrees and about 80 degrees, between about 15 degrees and about 75 degrees, between about 20 degrees and about 70 degrees, between about 25 degrees and about 65 degrees, between about 30 degrees and about 60 degrees, between about 35 degrees and about 55 degrees, between about 40 degrees and about 50 degrees, or about 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, or between a range of any two of aforementioned values. In some implementations, the angle associated with the exhaust cavities 112A may reduce the amount of recoil upon firing a projectile using a firearm. Since the exhaust cavities 112A are angled, the amount recoil generated (towards the proximal end 102 of the firearm suppressor 100) by the air exiting the firearm suppressor 100 may be reduced based in part of the angle associated with the exhaust cavities 112A.

The vanes 124 may be formed from the distal opening 122 and extend towards an outer circumferential edge of the distal end 104 (or the firearm suppressor 100). In some implementations, the vanes 124 may extend in a spiral manner from the distal opening 122 towards the outer circumferential edge of the distal end 104. The vanes 124 may define one or more channels 124A that are formed between the vanes 124 (for example, between each adjacent vanes 124). In some implementations, the one or more channels 124A formed between the vanes 124 may be in fluid communication with the bore 162 of the tube 160. When a bullet exists from the firearm suppressor 100 and travels through the bore 162, it may generate pressure within the tube 160 and may push gas through the distal opening 122 and the channels 124A as it exits from the firearm suppressor 100. As gas exits through the distal opening 122 and the channels 124A, the vanes 124 may advantageously redirect the gas to generate or exert a rotational force on the firearm suppressor 100. In some implementations, such rotational force may tighten the firearm suppressor 100 (e.g., on a firearm to which the firearm suppressor 100 is coupled).

Heat Dissipating Fins

The body 106 may include one or more fins 180 extending outwardly from an outer surface of the body 106. Optionally, the fins 180 may be arranged circumferentially (e.g., along an entire circumference) of the outer surface of the body 106. Alternatively or optionally, the fins 180 can extend longitudinally (e.g., parallel to a central axis of the firearm suppressor 100) along at least a portion of the length of the body 106. The fins 180 can define one or more channels 182 between adjacent fins 180. The fins 180 and the channels 182 can advantageously increase the surface area of the body 106, thereby improving the rate of heat dissipation or exchange via the body 106 of the firearm suppressor 100 (e.g., via convection heat transfer with air that flows over the fins 180 and channels 182).

In some implementations, the body 106 of the firearm suppressor 100 can have between about 20 fins and about 50 fins, such as approximately 40 fins 180. Optionally, the number of the fins 180 of the body 106 can vary depending on the size of the body 106, the dimensions of the fins 180, type of the firearm, rate of fire of the firearm, desired heat dissipation rate, and the like. The fins 180 can increase the surface area of the outer surface of the body 106, thereby increase the amount of heat dissipated from the firearm suppressor 100. An increase in the number of the fins 180 may result in increased rate of heat dissipation from the body 106 of the firearm suppressor 100.

The fins 180 may be arranged about the circumference of the outer surface of the body 106 such that each of the fins 180 may be evenly positioned around the circumference of the outer surface of the body 106. Even distribution of the fins 180 may advantageously provide even rate of heat dissipation from the body 106 of the firearm suppressor 100 thus may prevent uneven heat distortions of the firearm suppressor 100. In some implementation, the fins 180 may be unequally spaced or positioned about the circumference of the outer surface of the body 106.

In some implementations, the dimensions of the fins 180 and the channels 182 may be varied. Variation of the dimensions of the fins 180 and the channels 182 may lead to variations of the surface area of the body 106, thereby changing the rate of heat dissipation from the body 106.

In some implementations, angle between the fins 180 and the outer surface of the body 106 may be between about 0 degrees and about 90 degrees, between about 10 degrees and about 80 degrees, between about 20 degrees and about 70 degrees, between about 30 degrees and about 60 degrees, between about 40 degrees and about 50 degrees, or about 10 degrees, about 20 degrees, about 30 degrees, about 40 degrees, about 50 degrees, about 60 degrees, about 70 degrees, about 80 degrees, about 90 degrees, or ranges between any two of aforementioned values. In some implementations, as described above, the fins 180 may extend longitudinally (e.g., parallel to a central axis of the firearm suppressor 100) along at least a portion of the length of the body 106 and the angle between the fins 180 and the outer surface of the body 106 may vary along the central axis of the firearm suppressor 100. In other implementations, as described herein, the fins 180 may be arranged circumferentially (e.g., along an entire circumference) of the outer surface of the body 106 and the angle between the fins 180 and the outer surface of the body 106 may vary along the circumference of the outer surface of the body 106.

In some implementations, the dimensions of the fins 180 may vary. For example, as described herein, the fins 180 may extend longitudinally (e.g., parallel to a central axis of the firearm suppressor 100) along at least a portion of the length of the body 106 and the thickness of the fins 180 may vary along the central axis of the firearm suppressor 100. In another example, as described herein, the fins 180 may be arranged circumferentially (e.g., along an entire circumference) of the outer surface of the body 106 and the thickness of the fins 180 may vary along the circumference of the outer surface of the body 106. Similarly, the dimensions of the channels 182 (for example, width of the channels 182) may be varied. In some implementations, the dimensions of a fin 180 may be different from that of an adjacent fin 180.

Chambers and Chamber Separators

In the example illustrated in FIGS. 1A-1L, the firearm suppressor 100 may include a proximal chamber 140, a distal chamber 142, one or more intermediate chambers 144, one or more chamber separators 146, a tube portion 160, a bore 162, one or more openings 164, and one or more channels 164A. The tube 160 may include a proximal opening 120 at its proximal end and the distal opening 122 at its distal end. The proximal opening 120 and the distal opening 122 may be aligned with a longitudinal axis defined by the length of the firearm suppressor 100.

In the example illustrated in FIG. 1D, the proximal chamber 140 may be in fluid communication with the proximal cavity 110. For example, a projectile (for example, a bullet) entering the firearm suppressor 100 may travel through the proximal cavity 110 and enter into the proximal chamber 140. In some implementations, the proximal chamber 140 may be larger than all other chambers of the firearm suppressor 100. For example, the length of the proximal chamber 140 may be greater than that of other chambers. The distal chamber 142 may be a chamber positioned the closest to the distal end 102. Optionally, the firearm suppressor 100 may include one or more intermediate chambers 144. The intermediate chambers 144 may be chambers positioned between the proximal chamber 140 and the distal chamber 142. For example, in the example illustrated in FIG. 1D, the firearm suppressor 100 may include two intermediate chambers 144.

The chambers described herein may have circular cross-sections. The diameters of the chambers for a firearm suppressor, for example, the proximal chamber 140, the distal chamber 142, and the intermediate chamber(s) 144, may be the same or different. The diameters of the chambers can be between about 0.75 inches and about 2.5 inches, between about 1 inch and about 2.25 inches, between about 1.25 inches and about 2 inches, between about 1.5 inches and about 1.75 inches, or about 0.75 inches, about 1 inch, about 1.25 inches, about 1.5 inches, about 1.75 inches, about 2 inches, about 2.25 inches, about 2.5 inches, or a range between any two of aforementioned values. Depending on the size of projectile traveling through the firearm suppressor 100, the diameters of the chambers may vary to provide sufficient clearance for the projectile and to provide sufficient volume of space for lattice structures 190 to provide desired sound and/or pressure wave-splitting. In some implementations, the lattice structures 190 have lattice of varying geometries. In some implementations, the lattices of the lattice structures 190 may be anisotropic (that is, have different properties or geometries in different directions) or isotropic (that is, have the same property or geometry in different directions).

Each of the chambers of the firearm suppressor 100 may house lattice structures 190 that may dissipate pressure and sound waves generated from the firing of a projectile (for example, a bullet) through the suppressor 100. In some implementations, the lattice structures 190 may or may not be made of the same material as the other components, features, or parts of the firearm suppressor 100. In some implementations, the lattice structures 190 may be printed along with other components, features, or parts of the firearm suppressor 100. Additional descriptions for the lattice structures 190 may be further provided herein.

The chamber separators 146 may be integrated with the body 106 and the tube 160 of the firearm suppressor 100. The chamber separators 146 may serve as physical boundaries between each of the chambers, for example, the proximal chamber 140, the distal chamber 142, and the intermediate chambers 144, of the firearm suppressor 100.

In some implementations, as illustrated in FIGS. 1E-1G, the chamber separators 146 may include one or more openings 148 formed between the chamber separators 146 and the body 106. The openings 148 may allow the chambers of the firearm suppressor 100 to be in fluid communication with each other. For example, the openings 148 may allow the proximal chamber 140 and one or more of the intermediate chambers 144 to be in fluid communication with each other. Accordingly, gas can flow between the chambers via the openings 148. For example, as described herein, when a bullet enters the firearm suppressor 100, it may generate positive pressure within the firearm suppressor 100. The positive pressure may be generated from the air displaced by the bullet as it travels through the suppressor 100 and/or sudden increase in temperature caused by, for example, temperature of the bullet and/or friction between the bullet and a firearm. As the bullet enters into the proximal chamber 140, the gas in the proximal chamber 140 may expand and be pushed in a direction away from the proximal end 102 of the firearm suppressor 100. Some of the gas may enter into the bore 162 of the tube 160 while some of the gas may enter into an adjacent intermediate chamber 144 via the openings 148.

In some implementations, the height of the openings 148 may vary between the chamber separators. For example, the openings 148 for a chamber separator between the proximal chamber 140 and an adjacent intermediate chamber 144 may have a height that is greater than that of the openings 148 for a chamber separator between the distal chamber 142 and an adjacent intermediate chamber 144. The height of the openings 148 may vary between about 0.04 inches and about 0.1 inches, between about 0.045 inches and about 0.095 inches, between about 0.05 inches and about 0.09 inches, between about 0.055 inches and about 0.085 inches, between about 0.06 inches and about 0.08 inches, between about 0.065 inches and about 0.075 inches, or about 0.04 inches, about 0.045 inches, about 0.05 inches, about 0.055 inches, about 0.06 inches, about 0.065 inches, about 0.07 inches, about 0.075 inches, about 0.08 inches, about 0.085 inches, about 0.09 inches, about 0.095 inches, about 0.1 inches, or a range between any two of aforementioned values.

In some implementations, as illustrated in FIG. 1D, the chamber separators 146 may be sloped at an angle with respect a longitudinal axis defined by the length of the firearm suppressor 100 (or the body 106 or the tube 160). The angle between the longitudinal axis and the separators 146 may be between about 10 degrees and about 80 degrees, between about 15 degrees and about 75 degrees, between about 20 degrees and about 70 degrees, between about 25 degrees and about 65 degrees, between about 30 degrees and about 60 degrees, between about 35 degrees and about 55 degrees, between about 40 degrees and about 50 degrees, or about 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, or between a range of any two of aforementioned values. The sloped configuration of the chamber separators 146 may facilitate expansion and movement of gas from one chamber to another, for example, from the proximal chamber 140 to the adjacent intermediate chamber 144 by, for example, funneling the gas towards the openings 148 of the chamber separators 146. In some implementations, the angle between the longitudinal axis and the separators 146 may be between about 34 degrees and about 56 degrees.

The openings 164 may be formed on the tube 160 as shown in FIG. 1J. Each of the openings 164 may be associated with a corresponding, respective channel 164A that allow the bore 162 and the chambers be in fluid communication. For example, when a projectile (for example, a bullet) travels through the bore 162 of the tube 160, the gases inside the bore 162 may be expelled out through the openings 164 and the channels 164A. The openings 164 and the channels 164A may have circular cross-sections.

In some embodiments, the channels 164A may be angled to advantageously facilitate flow of gases. For example, the angles associated with the channels 164A may correspond to the angles associated with the chamber separators 146. Such configuration may reduce turbulence within the firearm suppressor 100 and facilitate the flow of gases towards the distal end 104.

The locations and positions of the chambers of the firearm suppressor 100 may facilitate distribution and dissipation of thermal energy (for example, heat) from the firearm suppressor 100 and into the atmosphere. For example, as described herein, the tube 160 may include the openings 164 and the channels 164A positioned such that they can be aligned with the chambers of the firearm suppressor 100. For example, in the example firearm suppressor 100 shown in FIG. 1D, the openings 164 and the channels 164A can be positioned with respect to the chambers (for example, the intermediate chambers 144 and the distal chamber 142) so allow gas to expand into the chamber when a projectile travels through the bore 162 of the tube 160.

The tube 160 of the firearm suppressor 100 may facilitate distribution and/or dissipation of thermal energy (for example, heat) from the firearm suppressor 100 and into the atmosphere. As described herein, the firearm suppressor 100 can include the chamber separators 146 that can define boundaries between the chambers of the firearm suppressor 100 (for example, the proximal chamber 140 and an adjacent intermediate chamber 142). The chamber separators 146 can conduct thermal energy from the tube 160 to the body 106 since the chamber separators 146 may be integrated with both the tube 160 and the body 106. In some implementations, there may be no thermal breaks or barriers between the tube 160 and the body 106.

Ridges

In some embodiments, the firearm suppressor 100 may include one or more ridges 170. The ridges 170 may be formed on an inner surface of the body 106. In some implementations, the ridges 170 may be formed on an outer surface of the tube 160. The ridges 170 may facilitate mixing of gases within the chambers. In some implementations, the ridges 170 may direct flow of gases within the chambers.

The ridges 170 may be triangular in shape, as shown in FIG. 1K. In the example illustrated in FIG. 1K, the sloped edges of the ridge 170 may direct the gases within a chamber. The edges of the ridge 170 may be at an angle with respect to the inner surface of the body 106. For example, the angle (for example, denoted as y in FIG. 1K) between the edges of the ridge 170 and the inner surface of the body 106 may be between about 20 degrees and about 70 degrees, between about 25 degrees and about 65 degrees, between about 30 degrees and about 60 degrees, between about 35 degrees and about 55 degrees, between about 40 degrees and about 50 degrees, or about 25 degrees, about 30 degrees, about 35 degrees, about 40 degrees, about 45 degrees, about 50 degrees, about 55 degrees, about 60 degrees, about 65 degrees, about 70 degrees, or a range between any two of aforementioned values. In some embodiments, the angle between the edges of the ridge 170 and the inner surface of the body 106 may be between about 40 degrees and about 50 degrees. Such angle may advantageously direct the flow of gases without impeding so as to facilitate the flow and/or mixing of the gases in chambers, for example, the distal chamber 142, of the firearm suppressor 100.

In some implementations, the ridges may be semi-circular, rectangular, or square in shape.

The ridges 170 may be formed in the distal chamber 142, the intermediate chambers 144, the proximal chamber 140, or any combination of the chambers of the firearm suppressor 100. For example, as illustrated in FIGS. 1D and 1L, the ridges 170 may be formed only in the distal chamber 142. While the example firearm suppressor 100 illustrated in FIGS. 1D and 1L have ridges 170 formed on the outer surface of the tube 160 and the inner surface of the body 106, it is contemplated that the ridges 170 may be formed only on the inner surface of the body 106, only on the outer surface of the tube 160, or both. In some implementations, the ridges 170 may be optional.

Lattice Structure

In one implementation, the lattice structure 190 can have one or more layers (e.g., multiple layers) of lattices made of metal (e.g., metal alloy, stainless steel, etc.). In one implementation, the lattice structure 190 can be defined by linear variation of connecting octahedral wire having a diameter of between 0.024 inches to about 0.012 inches. Advantageously, the lattice structure 190 can break up (e.g., dissipate, reduce) sound and pressure waves passing through the suppressor 100 from the firing of a projectile (e.g., bullet) through the suppressor 100.

The lattice structure 190 can have a plurality of voids. In one implementation, the lattice structure 190 in the distal chamber 142 can provide approximately 1:1 void-to-metal ratio (or void-to-structure ratio) throughout the lattice structure 190. In some implementations, where the lattice structure 190 has multiple layers of lattice, the different layers may be arranged so that openings in one layer of lattice structure are offset from (that is, do not align with) openings of lattice structure in an adjacent layer to thereby provide a discontinuous (for example, nonlinear) passage from a center (for example, along the central, longitudinal axis) of the lattice structure 190 to an outer surface of the lattice structure 190.

Optionally, the lattice structure 190 can be wrapped or fastened with one or more wires. Optionally, the lattice structure 190 can have a generally cylindrical shape with a central passage or bore. In some implementations, the lattice structure 190 can have an oval cross-sectional shape. In one implementation, the lattice structure 190 can optionally be a separate cartridge that is removable (for example, for cleaning).

In some implementations, the lattice structures 190 may or may not be made of the same material as the other components, features, or parts of the firearm suppressor 100. In some implementations, the lattice structures 190 are, for example, printed with the firearm suppressor and its parts, components, and features.

The lattice structure 190 advantageously provides sound and/or pressure wave-splitting in the firearm suppressor 100. As described herein, the lattice structure 190 may include lattice of same or varying geometries that may be isotropic or anisotropic. Such features can facilitate wave-splitting in the firearm suppressor 100.

Diffusion and dissipation in suppression is the rate at which particles and heat of expanding gases from an exiting gunshot can be controlled, absorbed and released into the atmosphere. It is unpredictable and rapid with a high level of fluctuating vorticity.

The lattice structure(s) 190 may advantageously dissipate heat by allowing the gases resulting from a gunshot to expand into a matrix of highly conductive material (for example, material with high heat conductivity) with no clear path of exit (for example, a nonlinear path, as described above). Advantageously, a ratio of open space to closed space (for example, space occupied by the lattice structure 190) provided by the lattice structure 190 may be between about 25% to about 75%, between about 30% to about 70%, between about 35% to about 65%, between about 40% to about 60%, between about 45% to about 55%, or about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, or a range between any two of aforementioned values. The ratio of the open space to the closed space may be referred as void-to-metal ratio herein.

In some implementations, the lattice structure 190 may have a void-to-metal ratio that is no more than 1:1 (that is, no more than 50% open spaces, or openings, relative to closed space provided by, for example, the wave-splitting lattice). In other implementations, the ratio of open space to close space may be between about 35% and about 45%. In some implementations, the ratio of open space to close space provided by the lattice structure 190 may be between about 39% and about 42%. In some implementations, the void-to-metal ratio may be between about 1:1 and about 3:1. this creates a condition of heat absorption and thermal inertia perpetuating through and dissipating from the firearm suppressor 100 (for example, via interaction between the gases flowing through the firearm suppressor 100 and the material of the lattice structure 190) to achieve equalization with atmospheric conditions. Additionally or alternatively, by adjusting the thickness of the lattice, the lattice geometry, and/or the void-to-metal ratio, the lattice structure 190 may break up sound and pressure waves into specific frequencies and amplitudes.

In some implementations, the void ratio the lattice structures 190 may be the same or different between the chambers (for example, between the proximal chamber 140 and the distal chamber 142). Optionally, the void ratio of the lattice structure 190 in the proximal chamber 140 may be greater than that of the lattice structure 190 in the intermediate chamber 144 and/or the distal chamber 142 (that is, the lattice structure 190 in the proximal chamber 140 is less tightly packed than the lattice structure 190 in the intermediate chamber(s) 144 and/or the distal chamber 142). Optionally, the void ratio of the lattice structure 190 in the intermediate chamber(s) 144 may be greater than that of the lattice structure 190 in the distal chamber 142 (that is, the lattice structure 190 in the intermediate chamber(s) 144 is less tightly packed than the lattice structure 190 in the distal chamber 142). The varying void ratio between the lattice structures 190 in the chambers can advantageously facilitate the airflow caused by a projectile passing through the firearm suppressor.

The lattice structure 190 can advantageously split sound and pressure waves generated by a projectile entering into the firearm suppressor 100. As described herein, the lattice structure 190 can include lattices of varying geometries or structures, including, for example, isometric, cubic, tetragonal, hexagonal, monoclinic, triclinic, and the like. The geometries or the structures of the lattices of the lattice structure 190 can split (for example, break up) various waves generated in the firearm suppressor 100, for example, sound waves and pressure waves. For example, by splitting the pressure waves traveling through the firearm suppressor 100, the force of the chaotic expansion of gases may be controlled and/or broken down (for example, dissipated), allowing the release of high pressures over a longer time period. This allows the expanding gases to expend much of their kinetic energy while flowing through the firearm suppressor 100 before exiting the firearm suppressor 100 and being released to the atmosphere.

As described herein, firearm suppressors get quite hot when in use. When projectiles, for example, bullets, are fired from a firearm, burning of gun powder generates significant amount of heat, which can cause rapid expansion of gases within the barrel of the firearm and subsequently, in the firearm suppressor. Additionally, the friction between the projectile and the barrel can generate heat. Because firing projectiles can introduce a large amount of heat in, for example, quick succession, it may be advantageous for the firearm suppressor to quickly distribute and dissipate heat.

In some implementations, the lattice structure 190 is integrated with an inner surface of the body 106. For example, the lattice structure 190 can include lattices, and the lattices can be made out of highly thermally conductive materials, for example, copper, different types of copper alloys, carbon steel, tungsten, and the like. Accordingly, the heat is generated within the firearm suppressor can be distributed towards the body 106 via the lattices of the lattice structure 190. Thus, integrating the lattice structure 190 with the body 106 can remove or reduce the number of thermal barriers or breaks (for example, an element having low thermal conductivity that prevent the flow of thermal energy between conductive materials) between inner portions of the lattice structure 190 (for example, portions of the lattice structure 190 proximate to the center, longitudinal axis of the firearm suppressor 100) and the outer portions of the lattice structure 190 (for example, portions of the lattice structure 190 in contact with the body 106). The heat distributed and/or dissipated to the body 106 can be removed from the firearm suppressor 100 and into the atmosphere, for example, via the fins 180 and the channels 182.

In some implementations, the lattice structure 190 can be integrated with the vanes 124 located about the distal end 104 (see FIGS. 1B, 1D, and 1L for reference) of the firearm suppressor 100. Accordingly, the thermal energy stored by the lattice structure 190 in the distal chamber 142 can be distributed to and/or dissipated via the vanes 124 and/or the channels 124A. This can advantageously reduce the amount of flash from the firearm suppressor 100.

In some implementations, the lattice structure 190 can be produced in a filter or cartridge like configuration and can optionally be removable, cleanable and replaceable. Advantageously, the lattice structure 190 may help extend the life of the firearm suppressor 100. For example, the diffuser 190 can be placed within the chambers described herein and about the tube 160. The lattice structure 190 may provide a cleaner environment within the firearm suppressor 100 for increased functionality and may facilitate prevention of molten particulates from escaping the end of the firearm suppressor 100, thereby advantageously reducing the flash and spark signature generated by traditional suppressor systems.

In some implementations, the lattice structure 190 can advantageously function as a flame arrester (or a deflagration arrester) by absorbing the heat from a flame front thus dropping the burning gas/air mixture below its auto ignition temperature. As such, the lattice structure 190 may extinguish the flame within the chambers of the firearm suppressor. For example, the heat may be absorbed through the voids (or passages) designed into the lattice structure 190. These voids may be designed, chosen, or dimensioned according to the MESG (Maximum Experimental Safe Gap) of the gas for a particular installation. These passages (or voids) can be regular or irregular in dimension and/or shape. The voids, for example, channels or openings, may advantageously be sized to inhibit (for example, stop) the flame front in the firearm suppressor 100 containing highly explosive gun powder and expanding gases.

Example Dimensions

In some implementations, the length of the firearm suppressor 100 (that is, the length along the longitudinal axis extending between the proximal end 102 and the distal end 104) may vary between about 3 inches and about 10 inches, between about 4 inches and about 9 inches, between about 5 inches and about 8 inches, between about 6 inches and about 7 inches, or about 3 inches, about 4 inches, about 5 inches, about 6 inches, about 7 inches, about 8 inches, about 9 inches, about 10 inches, or a range between any two of aforementioned values. Optionally, the length of the firearm suppressor 100 is about 6.9 inches.

In some implementations, the lengths of the chambers (that is, the length of the chambers along the longitudinal axis extending between the proximal end 102 and the distal end 104) of the firearm suppressor 100 may vary between about 0.5 inches and about 4 inches, between about 1 inch and about 3.5 inches, between about 1.5 inches and about 3 inches, between about 2 inches and about 2.5 inches, or about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, about 4 inches, or a range between any two of aforementioned values. The lengths of the chambers may or may not be the same. For example, the length of the proximal chamber 140 may be greater than that of the other chambers, for example, the distal chamber 142 and/or the intermediate chambers 144. Optionally, the length of the intermediate chambers 144 may be less than that of the other chambers, for example, the proximal chamber 140 and the distal chamber 140. In some implementations, the length of the proximal chamber 140 may or may not be greater than that of the distal chamber 142.

As described herein, the lengths of the chambers (for example, the proximal chamber 140, the distal chamber 142, and the intermediate chambers 144) can vary to change the rate or amount of heat dissipation, sound wave-splitting, and pressure wave-splitting.

In some implementations, the diameter of the proximal cavity 110 may vary between about 0.5 inches and about 1.5 inches, between about 0.6 inches and about 1.4 inches, between about 0.7 inches and about 1.3 inches, between about 0.8 inches and about 1.2 inches, between about 0.9 inches and about 1.1 inches, or about 0.5 inches, about 0.6 inches, about 0.7 inches, about 0.8 inches, about 0.9 inches, about 1.0 inches, about 1.1 inches, about 1.2 inches, about 1.3 inches, about 1.4 inches, about 1.5 inches, or a range of any two aforementioned values. Optionally, the diameter of the proximal cavity 110 may be about 0.96 inches.

In some implementations, the outer diameter of the firearm suppressor 100 may vary between about 1 inch and about 2.1 inches, between about 1.1 inches and about 2 inches, between about 1.2 inches and about 1.9 inches, between about 1.3 inches and about 1.8 inches, between about 1.4 inches and about 1.7 inches, between about 1.5 inches and about 1.6 inches, or about 1 inch, about 1.1 inches, about 1.2 inches, about 1.3 inches, about 1.4 inches, about 1.5 inches, about 1.6 inches, about 1.7 inches, about 1.8 inches, about 1.9 inches, about 2.0 inches, about 2.1 inches, or a range of any two aforementioned values. Optionally, the outer diameter of the firearm suppressor 100 may be about 1.6 inches.

Additional Examples of a Firearm Suppressor

FIGS. 2A-2L illustrate another example firearm suppressor 200. The parts, components and features of the suppressor 200 in FIGS. 2A-2L are similar to the parts, components and features of the suppressor 100 in FIGS. 1A-1L. Thus, references numerals used to designate the various components, parts and features of the suppressor 200 are identical to those used for identifying corresponding components, parts and features of the suppressor 100 in FIGS. 1A-1L. Therefore, the structure and description for the various parts, features and components of the suppressor 200 in FIGS. 2A-2L are understood to also apply to the corresponding parts, features and components of the suppressor 100 in FIGS. 1A-1L, except as described below.

As shown in FIGS. 2A and 2C, the proximal end 102 of the firearm suppressor can include a mating portion 108 that may include one or more of beveled edge 204 that can facilitate coupling between the mating portion 108 and a distal end of a firearm. Optionally, the beveled edge 204 may be flat. The beveled edge(s) 204 may be used as a gripping surface when coupling the firearm suppressor 100 with a firearm. For example, a wrench may be used against the beveled edge(s) 204 to grip the mating portion 108 and rotate the mating portion 108 against a distal end of a firearm.

As illustrated in FIGS. 2D and 21, the firearm suppressor 200 may include an additional chamber 212 surrounding at least a portion of the proximal cavity 110 (for example, space between a proximal opening of the mating portion 108 and the proximal chamber 140). The chamber 212 may be in fluid communication with the proximal chamber 140 so as to allow gases to flow from the proximal chamber 140 and enter into it.

The firearm suppressor 200 may include an additional chamber separator 210 that may be positioned between the proximal chamber 140 and the chamber 212. As discussed herein, the separator 210 may be sloped or angled with respect to the inner surface of the body 106 to, for example, facilitate flow of gases. The chamber separator 210 may include one or more openings 214 that allow the proximal chamber 140 and the chamber 212 to be in fluid communication (for example, gases can flow between the proximal chamber 140 and the chamber 212). As shown in FIGS. 2H and 2L, the separator 210 may include two rows of the openings 214. The rows of the openings 214 may be offset from each other to, for example, discontinuous (for example, nonlinear) passage between the proximal chamber 140 and the chamber 212.

In some implementations, the separator 210 may include a single row of the openings 214. In other implementations, the separator 210 may include more than two rows of the openings 214.

In some implementations, the length of the firearm suppressor 200 (that is, the length along the longitudinal axis extending between the proximal end 102 and the distal end 104) may vary between about 6 inches and about 13 inches, between about 7 inches and about 12 inches, between about 8 inches and about 11 inches, between about 9 inches and about 10 inches, or about 6 inches, about 7 inches, about 8 inches, about 9 inches, about 10 inches, about 11 inches, about 12 inches, about 13 inches, or a range between any two of aforementioned values. Optionally, the length of the firearm suppressor 200 is about 9.7 inches.

In some implementations, the lengths of the chambers (that is, the length of the chambers along the longitudinal axis extending between the proximal end 102 and the distal end 104) of the firearm suppressor 200 may vary between about 0.5 inches and about 4 inches, between about 1 inch and about 3.5 inches, between about 1.5 inches and about 3 inches, between about 2 inches and about 2.5 inches, or about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, about 4 inches, or a range between any two of aforementioned values. The lengths of the chambers may or may not be the same. For example, the length of the proximal chamber 140 may be greater than that of the other chambers, for example, the distal chamber 142 and/or the intermediate chambers 144. Optionally, the length of the intermediate chambers 144 may be less than that of the other chambers, for example, the proximal chamber 140 and the distal chamber 140. In some implementations, the length of the proximal chamber 140 may or may not be greater than that of the distal chamber 142.

In some implementations, the diameter of the proximal cavity 110 of the firearm suppressor 200 may vary between about 0.8 inches and about 1.5 inches, between about 0.9 inches and about 1.4 inches, between about 1 inch and about 1.3 inches, between about 1.1 inches and about 1.2 inches, or about 0.8 inches, about 0.9 inches, about 1 inch, about 1.1 inches, about 1.2 inches, about 1.3 inches, about 1.4 inches, about 1.5 inches, or a range of any two aforementioned values. Optionally, the diameter of the proximal cavity is about 1.125 inches.

In some implementations, the outer diameter of the firearm suppressor 200 may vary between about 1.5 inch and about 3.5 inches, between about 1.6 inches and about 3.4 inches, between about 1.7 inches and about 3.3 inches, between about 1.8 inches and about 3.2 inches, between about 1.9 inches and about 3.1 inches, between about 2.0 inches and about 3.0 inches, between about 2.1 inch and about 2.9 inches, between about 2.2 inch and about 2.8 inches, between about 2.3 inch and about 2.7 inches, between about 2.4 inch and about 2.6 inches, or about 1.5 inches, about 1.6 inches, about 1.7 inches, about 1.8 inches, about 1.9 inches, about 2.0 inches, about 2.1 inches, about 2.2 inches, about 2.3 inches, about 2.4 inches, about 2.5 inches, about 2.6 inches, about 2.7 inches, about 2.8 inches, about 2.9 inches, about 3.0 inches, about 3.1 inches, about 3.2 inches, about 3.3 inches, about 3.4 inches, about 3.5 inches, or a range of any two aforementioned values. Optionally, the outer diameter of the firearm suppressor 200 is about 2.5 inches.

FIGS. 3A-31 illustrate yet another example firearm suppressor 300. The parts, components and features of the suppressor 300 in FIGS. 3A-3I are similar to the parts, components and features of the suppressor 100 in FIGS. 1A-1L. Thus, references numerals used to designate the various components, parts and features of the suppressor 300 are identical to those used for identifying corresponding components, parts and features of the suppressor 100 in FIGS. 1A-1L. Therefore, the structure and description for the various parts, features and components of the suppressor 300 in FIGS. 3A-31 are understood to also apply to the corresponding parts, features and components of the suppressor 100 in FIGS. 1A-1L, except as described below.

In the example implementation shown in FIG. 3D, the firearm suppressor 300 may not include the tube 160 (or tube portion) that interconnects chamber separators. The firearm suppressor 300 may include one or more chamber separators 302 that each define an aperture 304 (e.g., a central aperture about the axis of the suppressor 300). The apertures 304 for the one or more chamber separators 302 may be aligned with each other along the longitudinal axis extending between the proximal end 102 and the distal end 104. When a projectile enters into the firearm suppressor 300, the projectile may travel through the chambers, for example, the proximal chamber 140, the intermediate chambers 144, and the distal chamber 142, via the apertures 304. The lack of the tube 160 may allow for increased dispersion of gases and pressure into lattice prior to exiting the suppressor 300 resulting in increased sound, pressure, flash, and/or recoil reduction. As shown in FIGS. 3E and 3F, the apertures 304 may be circular. The apertures 304 may have suitable dimensions to allow projectiles of different sizes to travel through the firearm suppressor 300.

In some implementations, the lattice structures 190 housed within the chambers (chambers separated by the chamber separators 302) may define an aperture to further facilitate projectiles traveling through the firearm suppressor 300. Optionally, the lattice structures 190 within, for example, the distal chamber 142 and the intermediate chambers 144, as shown in FIG. 3D, may be cylindrical in shape. Alternatively, the lattice structures 190 may be toroidal in shape.

In some implementations, the dimensions of the apertures of the lattice structures 190 may or may not be the same along the length of the chambers. For example, as illustrated in FIG. 3D, the lattice structure 190 within the proximal chamber 140 may have a proximal aperture and a distal aperture, where the diameter of the proximal aperture is greater than that of the distal aperture. In some examples, the lattice structure 190 in the proximal chamber 140 may taper from its distal portion (that is, portion proximate to an adjacent intermediate chamber 144) towards its proximal portion (that is, portion proximate to the proximal end 102 of the firearm suppressor 300). In some implementations, the tapering of the lattice structure 190 may correspond to the dimensions (for example, the diameter) of the proximal cavity 110 and the apertures 304.

In some implementations, such configuration (for example, tapering) of the lattice structure 190 may advantageously provide, for example, additional space for the air to expand when a projectile (for example, a bullet) enters the proximal chamber 140. By providing additional space for the air, the lattice structure 190 may prevent or reduce the amount of air resistance against the projectile by allowing the air to move into the additional space.

In some implementations, the lattice structures 190 may be sufficiently rigid to maintain the shape or the dimensions of the aperture.

In some implementations, the chamber separators 302 may be angled or sloped with respect to the inner surface of the body 106 as discussed herein. Optionally, the angle between the chamber separators 302 and the inner surface of the body 106 may be between about 40 degrees and about 50 degrees. Such configuration may allow the gas to be directed towards the openings 148 (for example, see FIGS. 3E and 3F) and allow the gases to flow from one chamber (for example, the proximal chamber 140) to another adjacent chamber (for example, one of the intermediate chambers 144).

In some implementations, different firearm suppressors may be used for different types of firearms or different types of projectiles. For example, the length of the suppressor may vary between different firearm suppressors, which may in turn change, including, but not limited to, the number of chambers, the dimensions of the chambers, gaps between the chamber separators, and the like.

In some implementations, the length of the firearm suppressor 300 (that is, the length along the longitudinal axis extending between the proximal end 102 and the distal end 104) may vary between about 3 inches and about 6 inches, between about 3.5 inches and about 5.5 inches, between about 4 inches and about 5 inches, between about 4.25 inches and about 4.75 inches, or about 3 inches, about 3.5 inches, about 4 inches, about 4.5 inches, about 5 inches, about 5.5 inches, about 6 inches, or a range between any two of aforementioned values. Optionally, the length of the firearm suppressor 300 is about 4.4 inches.

In some implementations, the lengths of the chambers (that is, the length of the chambers along the longitudinal axis extending between the proximal end 102 and the distal end 104) of the firearm suppressor 300 may vary between about 0.5 inches and about 3 inches, between about 1 inches and about 2.5 inches, between about 1.5 inches and about 2 inches, or about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, or a range between any two of aforementioned values. The lengths of the chambers may or may not be the same. For example, the length of the proximal chamber 140 may be greater than that of the other chambers, for example, the distal chamber 142 and/or the intermediate chambers 144. Optionally, the length of the intermediate chambers 144 may be less than that of the other chambers, for example, the proximal chamber 140 and the distal chamber 140. In some implementations, the length of the proximal chamber 140 may or may not be greater than that of the distal chamber 142.

In some implementations, the diameter of the proximal cavity 110 of the firearm suppressor 300 may vary between about 0.2 inches and about 1 inch, between about 0.3 inches and about 0.9 inches, between about 0.4 inch and about 0.8 inches, between about 0.5 inches and about 0.7 inches, or about 0.2 inches, about 0.3 inches, about 0.4 inches, about 0.5 inches, about 0.6 inches, about 0.7 inches, about 0.8 inches, about 0.9 inches, about 1 inch, or a range of any two aforementioned values. Optionally, the diameter of the proximal cavity 110 of the firearm suppressor 300 may be about 0.44 inches.

In some implementations, the outer diameter of the firearm suppressor 300 may vary between about 0.5 inches and about 2 inches, between about 0.6 inches and about 1.9 inches, between about 0.7 inches and about 1.8 inches, between about 0.8 inches and about 1.7 inches, between about 0.9 inches and about 1.6 inches, between about 1.0 inch and about 1.5 inches, between about 1.1 inch and about 1.4 inches, between about 1.2 inch and about 1.3 inches, or about 0.5 inches, about 0.6 inches, about 0.7 inches, about 0.8 inches, about 0.9 inches, about 1.0 inch, about 1.1 inches, about 1.2 inches, about 1.3 inches, about 1.4 inches, about 1.5 inches, about 1.6 inches, about 1.7 inches, about 1.8 inches, about 1.9 inches, about 2.0 inches, or a range of any two aforementioned values. Optionally, the outer diameter of the firearm suppressor 300 may be about 1.09 inches.

For example, one of the intermediate chambers 144 may be removed from the firearm suppressor 100 to decrease the length of the suppressor. FIGS. 4A-4L illustrate another example firearm suppressor 400. The parts, components and features of the suppressor 400 in FIGS. 4A-4L are similar to the parts, components and features of the suppressor 100 in FIGS. 1A-1L. Thus, references numerals used to designate the various components, parts and features of the suppressor 400 are identical to those used for identifying corresponding components, parts and features of the suppressor 100 in FIGS. 1A-1L. Therefore, the structure and description for the various parts, features and components of the suppressor 400 in FIGS. 4A-4L are understood to also apply to the corresponding parts, features and components of the suppressor 100 in FIGS. 1A-1L, except as described below. The firearm suppressor 400 may include three chambers (the proximal chamber 140, the intermediate chamber 144, and the distal chamber 142). In some implementations, one or more dimensions (for example, the length) of the chambers may be varied to change the length of the suppressor.

In some implementations, the length of the firearm suppressor 400 (that is, the length along the longitudinal axis extending between the proximal end 102 and the distal end 104) may vary between about 4 inches and about 8 inches, between about 4.5 inches and about 7.5 inches, between about 5 inches and about 7 inches, between about 5.5 inches and about 6.5 inches, between about 5.75 inches and about 6.25 inches, or about 4 inches, about 5.5 inches, about 6 inches, about 6.5 inches, about 7 inches, about 7.5 inches, about 8 inches, or a range between any two of aforementioned values. Optionally, the length of the firearm suppressor 400 is about 5.9 inches.

In some implementations, the lengths of the chambers (that is, the length of the chambers along the longitudinal axis extending between the proximal end 102 and the distal end 104) of the firearm suppressor 400 may vary between about 0.5 inches and about 3 inches, between about 1 inch and about 2.5 inches, between about 1.5 inches and about 2 inches, or about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, or a range between any two of aforementioned values. The lengths of the chambers may or may not be the same. For example, the length of the proximal chamber 140 may be greater than that of the other chambers, for example, the distal chamber 142 and/or the intermediate chambers 144. Optionally, the length of the intermediate chambers 144 may be less than that of the other chambers, for example, the proximal chamber 140 and the distal chamber 140. In some implementations, the length of the proximal chamber 140 may or may not be greater than that of the distal chamber 142.

Optionally, the diameter of the proximal cavity 110 of the firearm suppressor 400 may be about 0.96 inches.

In some implementations, the outer diameter of the firearm suppressor 400 may vary between about 1 inch and about 2.5 inches, between about 1.1 inches and about 2.4 inches, between about 1.2 inches and about 2.3 inches, between about 1.3 inches and about 2.2 inches, between about 1.4 inches and about 2.1 inches, between about 1.5 inches and about 2.0 inches, between about 1.6 inches and about 1.9 inches, between about 1.7 inches and about 1.8 inches, or about 1 inch, about 1.1 inches, about 1.2 inches, about 1.3 inches, about 1.4 inches, about 1.5 inches, about 1.6 inches, about 1.7 inches, about 1.8 inches, about 1.9 inches, about 2.0 inches, about 2.1 inches, about 2.2 inches, about 2.3 inches, about 2.4 inches, about 2.5 inches, or a range of any two aforementioned values.

The parts, components and features of the suppressor 500 in FIGS. 5A-5L are similar to the parts, components and features of the suppressor 100 in FIGS. 1A-1L. Thus, references numerals used to designate the various components, parts and features of the suppressor 500 are identical to those used for identifying corresponding components, parts and features of the suppressor 100 in FIGS. 1A-1L. Therefore, the structure and description for the various parts, features and components of the suppressor 500 in FIGS. 5A-5L are understood to also apply to the corresponding parts, features and components of the suppressor 100 in FIGS. 1A-1L, except as described below. The firearm suppressor may include three chambers (the proximal chamber 140, the intermediate chamber 144, and the distal chamber 142). However, the firearm suppressor 500 may be shorter in length than the firearm suppressor 400 due to the shorter lengths of the chambers. In some implementations, a firearm suppressor may not have any intermediate chambers 144.

In some implementations, the length of the firearm suppressor 500 (that is, the length along the longitudinal axis extending between the proximal end 102 and the distal end 104) may vary between about 3 inches and about 6 inches, between about 3.5 inches and about 5.5 inches, between about 4 inches and about 5 inches, between about 4.25 inches and about 4.75 inches, or about 3 inches, about 3.5 inches, about 4 inches, about 4.5 inches, about 5 inches, about 5.5 inches, about 6 inches, or a range between any two of aforementioned values. Optionally, the length of the firearm suppressor 500 is about 4.9 inches.

In some implementations, the lengths of the chambers (that is, the length of the chambers along the longitudinal axis extending between the proximal end 102 and the distal end 104) of the firearm suppressor 500 may vary between about 0.5 inches and about 3 inches, between about 1 inch and about 2.5 inches, between about 1.5 inches and about 2 inches, or about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, or a range between any two of aforementioned values.

Optionally, the outer diameter of the firearm suppressor 500 may be about 1.75 inches.

FIGS. 6A-6J illustrates yet another example firearm suppressor 600. The parts, components and features of the suppressor 600 in FIGS. 6A-6J are similar to the parts, components and features of the suppressor 100 in FIGS. 1A-1L. Thus, references numerals used to designate the various components, parts and features of the suppressor 600 are identical to those used for identifying corresponding components, parts and features of the suppressor 100 in FIGS. 1A-1L. Therefore, the structure and description for the various parts, features and components of the suppressor 600 in FIGS. 6A-6J are understood to also apply to the corresponding parts, features and components of the suppressor 100 in FIGS. 1A-1L, except as described below. In the example illustrated in FIG. 6D, The suppressor 600 has only the proximal chamber 140 and the distal chamber 142.

In some implementations, the length of the firearm suppressor 600 (that is, the length along the longitudinal axis extending between the proximal end 102 and the distal end 104) may vary between about 2 inches and about 5 inches, between about 2.5 inches and about 4.5 inches, between about 3 inches and about 4 inches, between about 3.25 inches and about 3.75 inches, or about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, about 4 inches, about 4.5 inches, about 5 inches, or a range between any two of aforementioned values. Optionally, the length of the firearm suppressor 600 is about 3.5 inches.

In some implementations, the lengths of the chambers (that is, the length of the chambers along the longitudinal axis extending between the proximal end 102 and the distal end 104) of the firearm suppressor 600 may vary between about 0.5 inches and about 2 inches, between about 0.75 inches and about 1.75 inches, between about 1 inch and about 1.5 inches, or about 0.5 inches, about 0.75 inch, about 1 inch, about 1.25 inches, about 1.5 inches, about 1.75 inches, about 2 inches, or a range between any two of aforementioned values.

Optionally, the length of the intermediate chambers 144 may be less than that of the other chambers, for example, the proximal chamber 140 and the distal chamber 140. In some implementations, the length of the proximal chamber 140 may or may not be greater than that of the distal chamber 142.

In some implementations, the diameter of the proximal cavity 110 of the firearm suppressor 600 may vary between about 0.2 inches and about 0.75 inches, between about 0.25 inches and about 0.7 inches, between about 0.3 inches and about 0.65 inches, between about 0.35 inches and about 0.6 inches, between about 0.4 inches and about 0.55 inches, between about 0.45 inches and about 0.5 inches, or about 0.2 inches, about 0.25 inches, about 0.3 inches, about 0.35 inches, about 0.4 inches, about 0.45 inches, about 0.5 inches, about 0.55 inches, about 0.6 inches, about 0.65 inches, about 0.7 inches, about 0.75 inches, or a range of any two aforementioned values.

It is contemplated that the number of the chambers described herein or the dimensions of the chambers changing the number of chambers or changing the dimensions (for example, the length) of the chambers may affect the overall suppression provided the a firearm suppressor. For example, a firearm suppressor may provide an improved sound and/or pressure wave-splitting if it has more chambers or has larger chambers to allow for, for example, increased rate or amount of wave-splitting. On the other hand, a firearm suppressor may provide reduced sound and/or pressure wave-splitting if it has less chambers or has smaller chambers. However, smaller firearm suppressors may still provide sufficient dissipation rate if used with a firearm configured for smaller projectiles.

In some implementations, the lengths of the firearm suppressors described herein may vary between about 2 inches and about 12 inches, between about 3 inches and about 11 inches, between about 4 inches and about 10 inches, between about 5 inches and about 9 inches, between about 6 inches and about 8 inches, or about 2 inches, about 3 inches, about 4 inches, about 5 inches, about 6 inches, about 7 inches, about 8 inches, about 9 inches, about 10 inches, about 11 inches, about 12 inches, or a range between any two of aforementioned values.

In some implementations, the lengths of the chambers described herein (for example, the proximal chamber 140, the distal chamber 142, and the intermediate chamber(s) 144) may vary between about 0.5 inches and about 5 inches, between about 1 inch and about 4.5 inches, between about 1.5 inches and about 4 inches, between about 2 inches and about 3.5 inches, between about 2.5 inches and about 3 inches, or about 0.5 inches, about 1 inch, about 1.5 inches, about 2 inches, about 2.5 inches, about 3 inches, about 3.5 inches, about 4 inches, about 4.5 inches, about 5 inches, or a range between any two of aforementioned values.

In some implementations, the diameter of the proximal cavities described herein (for example, the proximal cavity 110 of the firearm suppressor 100) may vary between about 0.3 inches and about 1.3 inches, between about 0.4 inches and about 1.2 inches, between about 0.5 inches and about 1.1 inches, between about 0.6 inches and about 1 inch, between about 0.7 inches and about 0.9 inches, or about 0.2 inches, about 0.3 inches, about 0.4 inches, about 0.5 inches, about 0.6 inches, about 0.7 inches, about 0.8 inches, about 0.9 inches, about 1.0 inches, about 1.1 inches, about 1.2 inches, about 1.3 inches, or a range of any two aforementioned values.

FIG. 7 illustrates a cross-section view of a yet another example firearm suppressor 700. The firearm suppressor 700 may include at least one chambers and chamber separators. Each of the at least one chambers of the firearm suppressor 700 may house or store lattice structure(s) 702 that can split pressure and sound waves generated by firing of a projectile, as described herein. The lattice structure 702 can include strands 704 that may be interlaced to form a lattice. The lattice may define voids 706 that pressure and sound waves can pass through. The strands 704 and the voids 706 may facilitate (together or separately) splitting of sound wave and/or pressure waves. Optionally, the strands 704 and voids 706 may facilitate dissipating and/or distributing thermal energy (for example, heat) generated by a projectile.

In some implementations, the lattice structure 702 and/or the strands 704 may be printed as a single piece along with the rest of the parts, components, and/or features of the firearm suppressor 700.

In some implementations, the lattice formed by the strands 704 may be cubic, tetrahedral, isometric, tetragonal, orthorhombic, monoclinic, triclinic, hexagonal, spiral, octahedral, or trigonal. In one implementation, any combination of aforementioned lattice types or any suitable lattice types may be utilized.

In some implementations, the lattice structures 702 in the chambers (for example, the proximal chamber 140, the distal chamber 142, and the intermediate chambers 144) may or may not be the same. For example, the lattice structure 702 in the proximal chamber 140 may have a first shape, and the lattice structures 702 in the chambers downstream from the proximal chamber 140 (for example, the distal chamber 142 and the intermediate chambers 144) may have a second shape. The first shape and the second shape may be the same or different.

The lattice structure 702 may fill the entire volume of the chambers. Optionally, the lattice structure 702 may fill only a portion of the entire volume of the chambers.

In some implementations, the lattice of the lattice structure 702 may be formed in a spiral manner. Such configuration of the lattice structure 702 may facilitate redirection of flow of gases within the firearm suppressor 700. For example, the lattice of the lattice structure 702 extend in a counter-clockwise direction when viewed from the proximal end 102 of the firearm suppressor 700. Accordingly, when gases flow through the lattice structure 702, the spiral lattice may advantageously redirect the gas to generate or exert a rotational force on the firearm suppressor 700. In some implementations, the lattice structure 702 may be integrated into various components of the firearm suppressor 700 (for example, connected to inner surfaces of the chambers and/or the outer surfaces of the tube). As such, the spiral lattice of the lattice structures 702 may be able to generate or exert additional rotational force on the firearm suppressor 700 when gases flow through the lattice structures 702.

In some implementations, various characteristics of the lattice structure 702 may be changed. For example, the size (or volume) of the voids 706 may be varied to, for example, vary the degree, rate, or amount of sound and/or pressure wave-splitting. In another example, the thickness of the strands 704 may be varied to change the ratio between the voids 706 and the lattice structure of the lattice structure 702.

In some implementations, the characteristics of the lattice structure 702 may vary between the chambers. For example, the proximal chamber 140 may have a lattice structure 702 with tetrahedral lattices while the distal chamber 142 may have a lattice structure 702 with hexagonal lattices. The different lattice structures 702 may be used to address the different environments, for example, pressure and magnitude of shockwave, associated with different chambers.

In some implementations, the lattice structure 190 housed in, for example, the distal chamber 142 of, for example, the firearm suppressor 100 may contain different types of lattices. For example, lattice proximate to the body 106 may have a first characteristic while lattice proximate to the tube 160 may have a second characteristics that may be different from the first characteristic. For example, the lattice proximate to the body 106 may have a different void ratio that the lattice proximate to the tube 160. Optionally and/or alternatively, the lattice proximate to the body 106 may hexagonal while the lattice proximate to the tube 160 may be tetragonal.

It is contemplated that varied characteristics (including, for example, lattice type, void ratio, void size, strand size, and the like) of the lattice structure 190 may be beneficial since, for example, certain types of lattices may be more efficient in breaking up (for example, splitting) sound waves and/or pressure waves having certain profiles (including, for examples, velocity, frequency, amplitude, wavelength, and the like) than breaking up (for example, splitting) sound waves and/or pressure waves having some other profiles. For example, sound wave and/or the pressure wave may be travel faster near the center, longitudinal axis of the firearm suppressor than near the body 106. As such, portions of the lattice structure 190 closer to the center, longitudinal axis of, for example, the proximal chamber 140 may have a lattice structure that may be more efficient at breaking up (for example, splitting) waves at a higher velocity whereas portions of the lattice structure 190 further away from the center, longitudinal axis of, for example, the proximal chamber 140 may have a lattice structure that may be more efficient at breaking up (for example, splitting) waves moving at a lower velocity.

In another example, for the lattice structure 190 in the proximal chamber 140, lattice proximate to the body 106 may have a first characteristic while lattice proximate to a center longitudinal axis of the proximal chamber 140 may have a second characteristics that may be different from the first characteristic.
